Whole-cell arsenite biosensor using photosynthetic bacterium Rhodovulum sulfidophilum : Rhodovulum sulfidophilum as an arsenite biosensor

An arsenite biosensor plasmid was constructed in Escherichia coli by inserting the operator/promoter region of the ars operon and the arsR gene from E. coli and the crtA gene, which is responsible for carotenoid synthesis in the photosynthetic bacterium, Rhodovulum sulfidophilum, into the broad-host...
